Definitions

  • the invention relates generally to devices for fastening objects, and more particularly to a fastener clip assembly for insertion into an engagement structure, such as a vehicle chassis, a hollow substrate, a wall, a plate, or any suitable surface.
  • an engagement structure such as a vehicle chassis, a hollow substrate, a wall, a plate, or any suitable surface.
  • a body panel refers to, for example, any interior or exterior body panel on a vehicle, a plastic interior trim piece, door panel, headliner or any interior trim piece. Additionally, the panel may be any suitable exterior body panel, such as a fender, bumper, quarter panel or door panel.
  • the chassis of the vehicle may include any substrate, plate, body panel, structural framework, chassis component or subcomponent, wall or any suitable object.
  • Fastener clips such as two-piece fasteners (multi-piece) are known for attaching body panels to an automobile chassis. Two-piece fasteners are used so that if the panels are removed after original installation, such as to service the components in the door, they may be pulled apart so that one portion remains attached to the sheet metal while the other remains attached to the trim panel. The two pieces may also be reattached after separation.
  • two-piece fasteners require manufacturing of multiple pieces and labor-intensive assembly of the two pieces and thus are relatively expensive.
  • One-piece fasteners are typically less expensive than two or multi piece fasteners.
  • One-piece fasteners have a base to attach to a body panel and a post attached to the base and wings attached at least to the top of the post at a tip of the fastener for fastening to a frame slot.
  • the forces on the wings are unequal since the wing closest to the slot edge will experience higher wing compression while the other wing will have insufficient springing force to engage the slot.
  • the clip is forced into the slot, such high forces on one wing may cause the wing to break off thus rendering the fastener incapable of fastening the body panel to the frame.
  • the broken, damaged or weakened wing can cause detachment of the body panel or contribute to rattles.
  • the wings of conventional fasteners have a sharp, unsmooth groove to engage the edge of the frame slot.
  • the sharp edges of the frame slot cut into the softer plastic and cut the groove.
  • the slots are typically formed in the frame of the vehicle, such as in an inner roof or door sheet metal structure, by punching the sheet metal. As the punch enters the sheet metal, the outer part of the sheet metal is pushed toward the inside and a metal puncture or ridge is formed on the inside of the sheet metal. The resulting slot edge on the outer part of the slot is relatively smooth; however, the inner part of the slot edge is sharp and rough.
  • Conventional fasteners typically do not adequately secure the panel to the vehicle chassis having variations in slot size and location or sheet metal with different curvature or thicknesses throughout.
  • Conventional single piece fasteners do not self-align themselves when the fastener and the body panel are misaligned and are prone to wing breakage such that the fastener cannot be re-attached.
  • conventional fasteners are not suitable when subjected to a variety of environmental conditions, such as in the presence of vibration at various levels of amplitude and frequency.
  • conventional fasteners of this type typically do not prevent or minimize the amount of buzzing, rattling or any other type of noise that may cause attention to the occupants of the vehicle or otherwise weaken the attachment.
  • Conventional fasteners do not adequately accommodate various levels of production
  • Figure 1 is a perspective view of a fastener clip configured to receive a nut, in accordance with some embodiments.
  • Figure 2 is a side view of a fastener clip configured to receive a nut, in accordance with some embodiments.
  • Figure 3 is another side view of a fastener clip configured to receive a nut, in accordance with some embodiments.
  • Figure 4 is a bottom view of a fastener clip configured to receive a nut, in accordance with some embodiments.
  • fastener clip 100 may be used to couple two objects together.
  • fastener clip 100 may be used to couple together a panel or another automotive component to an automotive chassis.
  • fastener clip 100 comprises four legs 10, with a pair of legs on each of side of the clip.
  • each leg in each of the pair of legs 10 may be coupled using threads 50 (with two sets of threads 50 in such an embodiment).
  • the material connecting pairs of legs 10 may be shaped into threads 50.
  • each of the two sets of threads 50 may be shaped into half barrels such that the two sets of threads 50 together form a threaded barrel. The two sets of threads may be appropriately offset to accommodate a screw being threaded through the formed barrel.
  • Fastener clip 100 may also include thread stops 60 at the top of threads 60.
  • Thread stops 60 may be configured to provide increased threading resistance to indicate to a user inserting a screw into the clip that the screw being threaded into fastener clip 100 has reached thread stops 60.
  • the treaded barrel may be configured to receive a threaded screw through opening 70.
  • fastener clip 100 may also include four wings/paddles 30 that may be respectively attached to each of legs 10.
  • Wings 10 may include ledges/cutouts 35, with which fastener clip 100, through wings 30 may be configured to attach to the edges/perimeter of a slot in chassis, for example.
  • Wings 30 may extend from the sides of legs 10 and then may be bent at an angle (close to 90 degrees, in some embodiments) toward feet 20 as is shown in the figures. As such, by compressing/pushing feet 20 toward each other, wings 30 and ledges 35 are pushed away from the edges/perimeter of a slot in a chassis thus releasing the clip from the chassis.
  • each of two feet 20 is configured to couple together a pair of legs 10 at the bottom of each of the pair of legs 10.
  • Feet 20 may be configured to provide a stop of how far into a slot fastener clip 100 may be inserted. That is, faster clip 100 may be inserted into a slot until the top surfaces of feet 20 engage the chassis.
  • feet 20 may be configured to facilitate removal of fastener clip 10 form a slot. For example, feet 20 may be pressed together toward the middle of slot, pushing legs 10 together and consequently squeezing the pairs of wings 30/ledges 35 together enough for fastener clip 100 to be released.
  • clip 100 may also include top portions 40, with each of top portions 40 coupling two of legs 10 together as is shown in the figures.
  • top portions may be shaped in such a way to facilitate the insertion of clip 100 into a slot.
  • top portions 40 may be appropriately tapered.
  • fastener clip 100 may be stamped/shaped out from a single piece of metal, such as steel. After cutting and bending into the right shape, the two half-barreled sides may be formed by pressing the two using some form of a half cylinder shape in each half.
  • FIG. 5 is a perspective view of a fastener clip attached to a chassis, in accordance with some embodiments.
  • Figure 6 is a side view of a fastener clip attached to a chassis, in accordance with some embodiments.
  • Figure 7 is another side view of a fastener clip attached to a chassis, in accordance with some embodiments.
  • fastener clip 100 may be configured to fit and attach to a slot in a chassis, such as slot 210 of chassis 200.
  • Feet 20 (not shown here) are configured to determine how far into the slot fastener clip 100 is permitted to be inserted.
  • Wings 30 are configured to slightly bend inwards as the fastener clip is being inserted into slot 210. Once fastener clip 100 is fully inserted into slot 210, ledges 35 reach the inner edge of slot 210, at which point, wings 30 spring back to substantially their original position. In addition, ledges 35 are now partially over the edge of the chassis in such a way that fastener clip 100 snaps into the slot and may not be easily extracted out of the slot.
  • fastener clip 100 may be removed from the slot by pushing together feet 20. Pushing the feet together also pushes the wings together, which causes ledges 35 to move back over the slot and way from the edge/perimeter of the slot, which allows faster clip 100 to be removed from the slot.
  • Screw 90 may be threaded into fastener clip 100 against both sets of threads 50, as the two sets of threads 50 together form a barrel into which screw 90 can thread.
  • Screw 90 may be used for attaching various components to chassis 200, such as panels, for example, by passing the screw first through a hole in the panel and then threading the screw into threads 50.
  • Thread stops 60 may be used as indicators of how far into fastener clip 10 screw 90 may be threaded, such that a user threading screw 90 into fastener clip 100 may be given feedback as to when the screw has reached the top of the clip.
  • the insertion of screw 90 into fastener clip 90 prevents the removal of the clip from the chassis as the presence of screw 90 prevents the pushing together of feet 20 and thus preventing the collapse of wings 30 and ledges 35 past the edge of slot 210.
  • the fastener clip may be removed only by removing screw 90 first. As such, when assembled fully, the security of attachment of components to the chassis is increased.
